Discrepancies in the marking of the first a
1 in bar 67 with an ornament should be analysed with taking into account the analogy with bars 71 and 75. In all three places GE has 
, while in FE (→EE) an ornament (
) appears only in bar 75. In that context both markings mean the same, yet it is not clear whether Chopin ultimately wanted to change for in bar 75 alone, or also in bars 67 & 71, where it was realised partly due to misunderstanding or oversight. Therefore we supplement the main text with the sign in parentheses.
